Vector2

A 2D vector using floating point coordinates.

Description

A 2-element structure that can be used to represent 2D coordinates or any other pair of numeric values.

It uses floating-point coordinates. By default, these floating-point values use 32-bit precision, unlike float which is always 64-bit. If double precision is needed, compile the engine with the option precision=double.

See Vector2i for its integer counterpart.

Note: In a boolean context, a Vector2 will evaluate to false if it's equal to Vector2(0, 0). Otherwise, a Vector2 will always evaluate to true.
